Why is the hydrolysis of an ester slow at the beginning and fast after some time?
(N/A) The hydrolysis of an ester can be represented as follows:
$Ester + H_2O \rightarrow Acid + Alcohol$
In this reaction,the acid produced acts as an autocatalyst.
Initially,the concentration of the acid is very low,so the reaction proceeds slowly.
As the reaction progresses,the concentration of the acid increases,which accelerates the rate of the reaction.
This phenomenon,where one of the products acts as a catalyst for the reaction,is known as autocatalysis.
